This was the overall winner. It shows the surface of the brain of a person with epilepsy. The image was taken before an intracranial electrode recording procedure, in which a flexible electrode grid was attached to the brain's surface. The patient was then taken to the telemetry ward, where their brain activity was recorded. The surgeon used the recordings to identify the specific areas of the brain to be removed in a subsequent operation. This patient made a full recovery and no longer suffers from seizures.
